Not according to plan

A fairly straightforward day was planned. Drive to Screwfix for Click and Collect order, then on to Tesco for weekly shop, home for lunch, then after remove old security light and install replacement. What could possibly go wrong? Leaving Tesco I encountered unexpected rain, but it was dry on arrival at home, but not for long. Drizzly rain stopped by mid afternoon, so the work began. The new light is, of course, an LED replacing  a unit which was powered by incandescent bulbs - big ones - so the placement requirement is different. Old rusty screws were also a problem, a new junction box was required  and other things governed by the Law of Sod also slowed progress, but at least most of the job is complete. This is a rather long explanation for an EB - leftover curry.
